I'm one of those and have difficulties with most bitter drinks as well so the problem compounds as I have to have more sugar than most to drink coffee or nonherbal teas. I found that the sugar free off brand winco red bull doesn't trigger the same sour/bitter for me which is great. I still stick with water, milk, barley tea, and hot cocoa (I make my own mix) for the most part.
